OPTIONSThe ORS-Compact Ultrastable Laser System is designed for high performancein demanding field applications. It delivers ultra-narrow linewidth laser lightwith outstanding frequency stability.
The system’s centerpiece is a high-finesse Fabry-Pérot cavity (cubic spacer
with a length of 5 cm) serving as a reference for a CW laser. The cavity is madeout of ultra-low expansion glass (ULE) and is operated in vacuum at the point ofzero thermal expansion. The reference cavity is actively decoupled from vibrations and acoustically isolated allowing for ultimate performance also in roughlaboratory environments. Rigid mounting of the cavity ensures portability without realignment of the optical paths.
The system is operated by the newest generation of Menlo Systems’ proprietary SYNCRO controller—a modular electronics platform designed for versatility and intuitive use. It incorporates all required electronics, e.g., a low-noise
laser driver and a very fast (analog) servo loop for laser frequency stabilization.
The user controls all parameters using either the 7” front-panel touchscreen ora GUI on a remote PC. The onboard software ensures automatic cavity locking
and system monitoring.
